Description
- The present invention relates to an ink jet recording apparatus using an ink jet printing head to perform printing a paper web with jets of ink and, in particular, an ink jet printing head of drop-on-demand type having a nozzle assembly which comprises a plurality of nozzle rows juxtaposed with one another in a direction of travel of the paper web to give the nozzle assembly a predetermined length in the direction of travel of the paper web, each of the nozzle rows having a multitude of ink nozzles juxtaposed with one another in a direction of width of the paper web.
- In an ink jet recording apparatus, it is an important requisite in providing good printing quality that the spacing between an ink jet printing head and the surface of a paper web (printing surface) be held constant. When use is made of an ink jet printing head which as in an ink jet recording apparatus as described, e. g., in
US Patent No. 6,003,988 , has a nozzle assembly made of only a single nozzle row having ink nozzles juxtaposed with one another in a direction perpendicular to a direction of travel of the paper web, namely in a direction of width of the paper web, the curving of a paper web traveling path with the paper web wrapped on a roller surface does not hinder printing on the paper web. However, when use is made of an ink jet printing head of drop-on-demand type which as in an ink jet recording apparatus as described, e. g., inJP H11-034360 A - There is also known as disclosed in
JP H05-124284 A JP 2000-141618 - In an apparatus of this type having a single ink jet printing head or a plurality of ink jet printing heads which is or are each disposed parallel to the paper surface between the guide rollers, the or each ink jet printing head may be an ink jet heat of drop-on-demand type and with a nozzle assembly having a plurality of nozzle rows juxtaposed with one another in a direction of travel of the paper web to be able generally to perform printing without adverse influence from a paper wrap angle for a guide roller because it is placed opposite and parallel to the paper surface between the rollers. However, in the ink jet recording apparatus of this type, if the rollers guiding paper while wrapping it on them are spaced from each other by a long distance, it is no longer possible to completely eliminate fluttering of the paper web traveling between the guide rollers. Fluttering of the paper web may occur between the rollers while it is driven to travel at a high speed or when the speed changes. Then, the result may be a disorder created in a printed image or a failure to print with due accuracy.
US-A-6 309 046 discloses an ink jet recording apparatus having an ink jet printing head for printing a paper web guiding to travel in an arc configuration on a plurality of guide rollers. - Made to solve the problems mentioned above, the present invention has for its object to provide an ink jet recording apparatus which is cable of printing a paper web in a state free from paper traveling fluttering irrespective of short and long distance between rollers so that an accurate printing can be performed by an ink jet head with a nozzle assembly having a plurality of nozzle rows juxtaposed with one another in a direction of travel of the paper web.
- In order to achieve the object mentioned above, there is provided in accordance with the present invention an ink jet recording apparatus as defined in
